20 Most Recent Honda Pressure Washer PSI 3000 - Page 4 Questions & Answers

Your pressure relief valve may not be working. If that happens when you shut off your spray gun, then pump is dead heading, stopping the motor. If this is the case it stops dead, not coasting. Either replace the pressure adjusting relief valve or remove it, and disassemble it and clean it.

it only will pull soap with the large hole tip or no tip very low pressure

could be running lean try setting up fuel intake a bit richer

Oil alert or the module where the oil alert wire plugs in to could be faulty. You can remove all the wires at the coil for test including the kill switch wire (always use a new spark plug for test, then place the new plug in stroage for later use). I test the coil off the engine on a growler. If the oil alert components are faulty, do not repair. Just check the oil more often. Good luck

Usual cause is the water admittance valve that regulates the pressure is stuck. The valve shuts off incoming water when pressure is up and then when wand is triggered and pressure drops it lets more water in. Remove the valve spool. Replace the O rings. Clean the bore with crocus cloth on a dowel rod. Lube with plumber's grease and re-assemble taking care that the spool and spring are assembled correctly. All will be well!

no pressure when trigger pulled. pulled brass head and the three pistons are moving .don't know where to look for something plugged or what that is not compressing water or letting compressed water through .was working good ,stopped for a break turned back on and no pressure.thanks

Hi and welcome to FixYa I am Kelly.
Things that cause this symptom are:
1. Debris in the carb float bowl
- Remove the carb float bow nut and clean out the bowl, the bowl but and up inside the treaded area of the bowl nut is the main fuel jet. Make sure to clean that also. You can try carb cleaner but sometimes the jet has to be removed to clear it.
2. Fuel selector sediment bowl is full of debris.
- Unscrew the sediment bulb under the fuel selector and dump out the sediment
3. Dirty fuel filter (if used)
- Check fuel flow at the carb main fuel line connection. If should fill a spray paint can lid in about 8 seconds. Anything less and you need to look at the fuel filter or fuel tank exit port as a source of restrictions.
Once you have good flow here you need to check fuel flow at the float needle.
4. Debris in the fuel float needle seat. Another flow check with a spray paint can lid catch basin.
- The spray paint can lid should fill up in around 10 seconds when you turn on the fuel selector.
Poor fuel flow here and you have to remove the float, hinge pin and float needle. Then spray into the float needle hole with carb cleaner with the MAIN FUEL SUPPLY HOSE DISCONNECTED. Also spray into the main fuel line connection so that any debris is removed.

Performing the above steps should improve your engine performance dramatically. If you still have the problem after performing the above steps respond with your ENGINE MODEL NUMBER and there is more that can be done.

Thanks for choosing FixYa, Kelly

Pressure washer are pretty simple, a few pistons and a spring device to control the pressure. The problem could be a broken part inside the pump itself. With any luck it could be the linkage between the pump and the motor. If there is a oil window in the pump or a pump oil fill plug open this and with the engine switched off slowly pull the starter cord and see if the pump works are moving. (don't do it fast or let the engine start or there will be oil everywhere.) this will tell you if the pump is working. It could also be the diverter this wold be harder to diagnose you could go and replace the whole pump also.

ereplacementparts.com or jackssmallengine repair.com. Why do you think you need a new pump. If you give me more info maybe I can help.

It sounds like your carburetor float is stuck open, which would explain the flooding, the white smoke, and the gas coming out of the exhaust. Sounds like you may have gotten a faulty carburetor. If you can, I would return it where you bought it and get a replacement. Else, you will need to have the carburetor rebuilt, or have the valves checked out.
